Description
Technical field
Certain embodiments of the present invention is the limit Sealing Technology about vacuum insulated glass building (vacuuminsulatingglass (VIG)) parts.Especially certain embodiments of the present invention relates to increasing the amount being used for forming the ferrous oxide (Ferrousoxide) that limit seals in glass dust (glassfrits) (such as lead-free glass powder), so that the amount that glass dust absorbs infra-red radiation increases.The technical merit of some preferred embodiment can make limit seal process shorten to several minutes from a few hours.Additionally the technology of some embodiment is likely to some or all of vacuum insulation assemblies are exposed to infrared radiation source (infraredsource (s)), because the ratio substrate of glass dust heating is fast, thus can reduce first substrate and/or second substrate fusing and lose the probability of heat treatment (HT) stress (such as temper stress (temperstrength)).In certain embodiments, coefficient (frit ' the sglassredox) (FeO/Fe of the glass redox reaction degree of glass dust2O3) it is preferably at least the coefficient (FeO/Fe of the glass redox reaction degree than any one (or higher that) substrate2O3) high by about 0.02, more preferably at least than the coefficient (FeO/Fe of the glass redox reaction degree of any one (or higher that) substrate2O3) high by about 0.04, and it most preferably is the coefficient (FeO/Fe of the glass redox reaction degree than any one (or higher that) substrate2O3) high by about 0.06.
Background technology
VIG unit is well known in the art.Such as, it just has disclosure in american documentation literature, and the patent No. listed below is 5,664,395,5657,607 and 5, and the american documentation literature of 902,652 can be for referencial use.
Fig. 1-2 illustrates common vacuum insulated glass building (VIG) parts.VIG unit 1 includes the glass substrate 2 and 3 at two intervals, surrounds evacuation of air or low pressure space between the two glass substrate.The arrangement that sheet glass/substrate 2 and 3 is sealed with pillar or partition 5 by peripheral seal or the limit of fusion weld glass (fusedsolderglass) 4 connects each other.
Pumping pipe 8 and be soldered glass 9 tight seal to hole 10, this hole 10 is the bottom that the inner surface from sheet glass 2 passes to the depression position 11 being positioned at sheet glass 2 outer surface.Air exhauster (vacuum) is connected to and pumps pipe 8 in order to evacuate the internal cavities between substrate 2 and 3, thus so as to producing area of low pressure or low-voltage space 6.After evacuation, pipe 8 is melted so that vacuum seals.Depression position retains the pipe 8 sealed.Also chemical absorbent (getter) 12 can be provided with inside depression position 13.
Manufacture is as follows with the process of the conventional vacuum IG unit that fusion weld glass envelope seals 4.Glass dust in solution (finally can form melten glass limit and seal 4) is initially deposited on the periphery around substrate 2.Another substrate 3 is put into the above partition 5 and described glass dust/solution to be pressed from both sides between which of substrate 2.Be heated to the temperature of about 500 DEG C including the described whole assembly of sheet 2, sheet 3, partition and encapsulant, on this temperature spot, after described glass powder, infiltration to the surface of described sheet glass 2,3 and ultimately forms peripheral seal or limit seals 4.This temperature of about 500 DEG C is kept one to eight hours.After described peripheral/edge seal 4 and the sealing around pipe 8 are formed, described assembly is cooled to room temperature.It is to be noted and illustrate that on the hurdle 2 of american documentation literature (patent No. is 5,664,395) temperature that the treatment temperature of conventional vacuum insulating glass is about at 500 DEG C keeps one hour.The inventor Corinth (Collins) of above-mentioned patent by human relations once, Tener and Corinth (Lenzen, Turner and Collins) " ThermalOutgassingofVacuumGlazing " that make points out " current limit sealing technology process is very slow: the temperature of sample generally rises 200 DEG C per hour; and the certain value within the scope of from 430 DEG C to 530 DEG C keeps one hour, described definite value changes according to the difference of the composition of melten glass ".Limit forms low-voltage space 6 by described pipe evacuation after sealing 4 formation.
Unfortunately, people form high temperature residing when limit seals 4 and long heat time heating time without wishing to occurring in described whole assembly, when especially needing to use hot reinforced glass substrate 2,3 or reinforced glass substrate 2,3 in described VIG unit.As shown in Figure 3-4, safety glass loses temper stress with the heat time heating time being exposed in high temperature.And, low-emission coated (low-Ecoating (s)) is very disadvantageous by so high treatment temperature, described low-emission coated may be used on one or two described glass substrate in some cases.
Fig. 3 illustrates complete hot armorplate glass is how to expose, in different time sections, the chart losing initial temper stress at different temperatures, and wherein initial center tension is per inch 3200MU.X-axis in Fig. 3 is exponentially with hour for unit express time (from 1 hour to 1000 hours), and y-axis represents is the percentage ratio of the initial temper stress retained after beat exposure.The chart of Fig. 4 is similar to Fig. 3, simply the x-axis in Fig. 4 exponentially extend from zero to one hour different.
Shown in Fig. 37 different curves, each curve represents the different temperatures (representing (°F) with degrees Fahrenheit) being exposed to.Described different curve/line is 400 °F (being arranged in the top of Fig. 3 chart), 500 °F, 600 °F, 700 °F, 800 °F, 900 °F and 950 °F (being arranged in the bottom of Fig. 3 chart).900 °F are equivalent to 482 DEG C, and it is in Fig. 1-2 and is formed within the scope that aforementioned normal melt glass envelope seals 4.Therefore it is noted that Fig. 3 is numbered the curve of 900 °F of 18.As shown, at this temperature the temper stress that (900 °F or 482 DEG C) remained through 1 hour is only initial 20%.So serious temper stress (temperstrength) loss (such as 80%) yes it is undesirable that.
In figures 3-4, it is pointed out that compared with keeping 1 hour with at 900 °F, in time hot tempering sheet being heated to 800 °F (about 428 DEG C) and keeps one hour, be retained in temper stress therein much bigger.After keeping 1 hour under 800 °F, such sheet glass remains with the initial temper stress of 70%, and this situation is substantially better than the initial temper stress less than 20% keeping the time of identical length to retain under 900 °F.
Except need not by whole parts heat the long time another advantage is that the stay material that can use lower temperature.This is perhaps needs in some cases.
Even with non-reinforced glass substrate, the high temperature being applied on described whole vacuum insulated glass building assembly may melt described glass or introduce stress.These stress may increase described glass deformation and/or the probability broken.
Sometimes use unleaded powder to form limit to seal.Although having the unleaded powder of a lot of reasons advantageous applications (such as from the angle of protection environment), but the use that unleaded powder seals as the limit of VIG unit being pretty troublesome sometimes.Such as, it is believed that the fusing point of the obtainable unleaded powder of current all commercial sources is all located in the scope of 500 DEG C to 600 DEG C.It is known that the softening point (softeningpoint) of the close soda-lime glass (sodalimeglass) possibly serving for glass substrate in described VIG unit of these temperature.It is therefore desirable to the technique currently melting unleaded powder generally can not soften the described substrate finally constituting described VIG unit.It addition, described substrate is exposed in so high temperature generally causes them and loses at least some of stress obtained in heat treatment (HT) period.Such as, tempering soda-lime glass substrate actually can lose tempering effect (de-temper) sometimes at some temperature.Additionally, the manufacture process of described VIG unit generally expends the long period, need to reach these high temperature within the time period and then cool down again.Correspondingly, common unleaded powder can cause some or all of problem same or analogous with the problems referred to above.
Therefore, it is required for providing the limit of well-formed to seal between relative sheet glass for VIG unit and manufacture method thereof technically.VIG unit for including safety glass sheet is also required to form peripheral seal technically, so that the reservation of described sheet glass is than the more initial temper stress using conventional vacuum insulating glass manufacturing technology to obtain, in order to form the sealing of melten glass limit, whole parts are heated in described conventional vacuum insulating glass manufacturing technology.To manufacturing unleaded powder and/or being also highly desirable by the improvement in the method in unleaded power applications to vacuum insulated glass building.

Detailed description of the invention
Certain embodiments of the present invention relates to peripheral seal or the limit sealing of the improvement of vacuum insulated glass building window component and/or its preparation method." periphery " and " limit " herein seals and does not refer to that described sealing is exactly on the absolute periphery being positioned at described parts or limit, and refers at least part of limit being located near or at (such as in about two inch range) described at least one substrate of parts of described sealing.Similarly, " limit " described herein is also not necessarily limited to the limit that glass substrate is absolute, and refers to and can include being positioned on the absolute limit of described substrate or the region of neighbouring (such as at about two inch range).Further, " the vacuum insulated glass building assembly " said here refers to that the limit of described vacuum insulated glass building is sealed the intermediate products being evacuated before (evacuation) described depression position with it, for instance it substrate including two parallel spaced apart and glass dust.Have again when described glass dust be referred to herein as at one or more than one described substrate " on ", or by one or more than one described during substrate institute " support ", this does not mean that described glass dust must be directly touch described substrate yet.That is " on " contain directly and on non-direct contact, even if therefore also having other materials (such as coating layer and/or thin film) between described substrate and described glass dust, it is also possible to think that glass dust is on substrate.
The time forming some process that limit seals preferably is shortened to several minutes from a few hours by certain embodiments of the present invention.Certain embodiments of the present invention, it is also preferred that make the substrate of final vacuum insulated glass building product retain more heat treatment stress (such as temper stress), also simplifies the set-up procedure of manufacture simultaneously.
In certain embodiments ferrum oxide (ironoxide) is joined in the formula of existing glass dust.This makes described glass dust enhance the ability that absorption infrared energy (wave-length coverage of such as absorbed energy is 0.9-1.2 micron) radiates in the seal process of described limit.More particularly, the present inventor accounts for, by adjusting ferrous oxide (ferrousoxide), the advantage that the ratio of ferrum oxide total amount achieves some embodiment in the preparation process of described VIG unit.
In described glass and its colorant potion the total amount of ferrum according to general custom at this with Fe2O3Form embody.But this is not say that all of ferrum is essentially all with Fe2O3Form exist.Similarly, even if the ferrum of ferrous state is likely to be not all exist with the form of FeO in described glass, but the total amount of the ferrum of ferrous state (ferrousstate, i.e. ferrous iron) is expressed as the form of FeO at this.The ferrum (such as FeO) of described ferrous state accounts for the ratio of total amount ferrum for determining the state (such as, the redox condition coefficient (glassredox) of glass) of the redox condition of described glass.At this, the redox condition coefficient table of glass is shown as FeO/Fe2O3Ratio, its percentage by weight (%) shared by ferrum being ferrous state (being expressed as FeO) (is expressed as Fe than the total amount of upper ferrum2O3) shared by percentage by weight (%).Therefore, Fe2O3Represent total iron at this, and FeO represents with the ferrum that ferrous state exists.Ferrous state (Fe2+；FeO) ferrum is blue-green coloring agent, and ferric state (Fe3+) ferrum of (ferricstate) is yellow-green coloring agent.
Above-mentioned is the definition of the redox condition coefficient to glass.But, the redox condition coefficient of batch redox condition coefficient (batchredox) and glass is different.A batch redox condition coefficient known in the art is generally based on following definition.Every kind of composition in batch is all assigned with a redox condition coefficient value, and described batch redox condition coefficient is to be calculated by the sum of above-mentioned coefficient value to get.Described calculating is based in every 2000 kilograms of sands the amount of composition.Described batch of redox condition coefficient value is for calculating glass preparation (such as from described batch) is front.To how determining that " batch redox condition coefficient " has detailed discussion in the redox condition coefficient value concept shown by glass technology expert W. Simpson and D.D. mayer (W.SimpsonandD.D.Myers) and application (Theredoxnumberconceptanditsuse) (1977 or 1978) thereof, using its full disclosure in this as reference.On the contrary, as previously mentioned, the redox condition coefficient of described glass is calculated by spectroscopic data (spectraldata) after glass preparation, and it accounts for the percent ratio (such as passing through spectrum) (through chemical analysis) of total iron-holder in glass for FeO.
Table below includes in some embodiment with iron content (Fe total in the wavelength transfer of heat correspondence glass dust of 1000 nanometers (nm)2O3Weight relative to the gross weight of glass).Similarly, Fig. 5 transmits corresponding total iron-holder with the heat of the wavelength of 1000 nanometers (nm).
Based on the information included in upper table and Fig. 5, the inventors found that the coefficient (FeO/Fe of the redox condition of glass in described glass dust2O3) it is preferably 0.20 to 0.30, more preferably 0.21 to 0.28, and it most preferably is 0.22 to 0.25.Present inventor have further discovered that total iron-holder is (with containing Fe2O3Amount represent) be preferably 0.5% to 5%, more preferably 0.75% to 3%.As noted above, an aspect of some embodiment relates to the coefficient (FeO/Fe of the redox condition of glass in the glass dust provided2O3) higher than the coefficient (FeO/Fe of the redox condition of glass in two substrates in described VIG unit2O3).Therefore, corresponding to the above-mentioned value (corresponding to the coefficient of the redox condition of glass in described glass dust) of the coefficient of the redox condition of glass in described substrate, in described glass dust, the coefficient of the redox condition of glass is preferably up to enclose high level than upper demonstration.In certain embodiments, the coefficient (FeO/Fe of the redox condition of glass in described glass dust2O3) preferably than the coefficient (FeO/Fe of the redox condition of glass in described substrate2O3) at least high about 0.02 (or higher), more preferably than the coefficient (FeO/Fe of the redox condition of glass in described substrate2O3) at least high about 0.04 (or higher), and most preferably be than the coefficient (FeO/Fe of the redox condition of glass in described substrate2O3) at least high about 0.06 (or higher).
Although the wavelength of the infrared energy radiation provided is 1000 nanometers, but for the glass dust in the seal process of described limit, described wavelength preferably range from such as 0.9-1.2 micron (microns).In the coefficient range of the redox condition of above-mentioned glass or in similar scope, the amount of the infrared energy transmitted by the glass dust of some embodiment is reduction of.Such as, preferably by the infrared energy of glass dust transmission less than 35% in some embodiment, more preferably less than 15%, it is still more preferably from less than 10%, and most preferably is less than 5%.
Described glass dust in some embodiment produces some actual beneficial effect.Such as, owing to described glass dust absorbs infrared energy (such as referred to above), the speed of its heating is faster than common heating.Certainly, the heating process of some embodiment can be shortened into several minutes by a few hours (heating for common).Such as, some embodiment can reach the temperature of glass dust and rise to 450 DEG C in 10 minutes or in shorter time, and this temperature can cause described glass powder.This temperature of 450 DEG C will lower than the temperature of 500-600 DEG C in common heating process.Using the described technology in some embodiment, the temperature melting described glass dust utilizing 400-425 DEG C in 10 minutes or similar time periods is possible.This can be realized by the amount of ferrous oxide in increase glass dust.Therefore in certain embodiments, the time melting described glass dust can shorten.
By relative to the iron-holder of described glass substrate to the ferrous oxide providing increment in described glass dust, it is possible for being exposed in the radiation of described infrared energy source by some or all complete intermediate modules in certain embodiments.This is because the ferrous oxide of increment is conducive to heating in described glass dust, for instance, will faster than the heating to described glass substrate to the heating of described glass dust.Therefore, some or all of glass substrates are heated to the first temperature levels, and can be heated to the second temperature levels at glass dust described in the time being substantially the same, and the temperature of wherein said second temperature levels is higher than the temperature of described first temperature levels.On the contrary, described glass substrate is heated to the temperature identical or closely similar with described glass dust by conventional oven heating process typically.
Therefore in certain embodiments, even after fusion process, it is shortened by, to described glass substrate heat time heating time and the temperature reducing described glass substrate, the described glass substrate of VIG unit to be made to keep the increment of heat treatment stress (such as temper stress).In certain embodiments, the heat treatment stress of 50% can at least be kept, more preferably at least 65%, still more preferably at least about 70%, and most preferably at least about 75-80%.
Structure technical process is made to become simple the technology that whole parts are all exposed in infrared radiation source in certain embodiments.
As noted before, embodiment described herein is preferably used lead-free glass powder.Such as, ferrum oxide is added in current glass dust formula, for instance, make the coefficient of the redox condition of described glass reach above-mentioned scope and/or similar scope.Although some embodiment relates to " lead-free glass powder ", but it is understood that for such glass dust is not unleaded completely.It is to say, still can be considered " unleaded " containing a small amount of plumbous glass dust.
